Which radars cover Ulmer?
The closest NEXRAD Doppler radar is KCLX (Charleston, SC), about 32 miles south-southeast. Radar beams climb as they travel, so the height of the lowest scan over town decides how low in a storm the radar can see.
| Radar | Distance | Lowest beam over Ulmer | View |
|---|---|---|---|
| KCLX Charleston, SC | 32 mi south-southeast | 2,000 ft | Excellent — the lowest scan sees close to the ground |
| KCAE Columbia, SC | 59 mi north | 4,400 ft | Good — most storms and steady rain or snow show clearly |
| KJGX Robins AFB, GA | 128 mi west-southwest | 14,000 ft | Limited — the beam overshoots the lowest part of storms |
Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
